Ok..I connected a yellow RCA cable (video) cable from coaxial of my receiver to STB Coaxial. I get the vocals in center speaker although I dont think this is the same clarity as my HDMI sound from the tata sky HD box earlier. maybe the RCA does not carry the entire sound signals.
Also earlier when I went from other channels to 565 and 567, the display changed from Stereo or Dolby movie and such to DD Digital...but now the display doesnt change when I go from non HD channel to HD channel..so I guess the RCA is not the right way to go about...have to adjust till I get an optical cable.
Anyone know where the cheapest place to get optical cable?
Stop doing that - you may damage the port!!!
You can get optical/coaxial cable at any sony/samsung/panasonic etc showroom or landmark or croma or ezone - basically wherever audio/video/computer & electonic products are sold - I got one optical cable from the local electrical shop for some <150 bucks.
